New technique measures mass of exoplanets

To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of these far-off worlds are habitable requires knowing an exoplanet’s mass — which can help tell scientists whether the planet is made of gas or rock and other life-supporting materials.

'Hints' found of Higgs boson, says CERN

Well, no definite proof - but scientists at CERN say they've seen 'tantalising hints' of the Higgs boson, and that they've narrowed the range of mass it could have - if it exists.

Earth's sixth mass extinction could already be underway

Life on earth is on the verge of a mass extinction comparable to that which wiped out the dinosaurs, scientists at UC Berkeley have warned.

Aftershock: Chilean quake shortened Earth days

A JPL research scientist has hypothesized that the recent magnitude 8.8 earthquake in Chile shortened the length of each Earth day by approximately 1.26 microseconds, or one millionth of a second.
